Korkmaz, Aysun published the artcileAsymmetric phthalocyanines conjugated on silica for the photocatalytic degradation of organic pollutants synthesis, characterization and investigation of the photophysicochemical properties, SDS of cas: 91-15-6, the main research area is phthalocyanine silica organic pollutant photocatalytic degradation photophysicochem property.

A series of novel asym. metallo (Mg, Zn and Ga) phthalocyanines were synthesized using different ratios of starting materials. After purification, these compounds were obtained in high yields. The asym. phthalocyanines were characterized by UV-visible (UV-vis), IR (IR) and 1H NMR spectroscopy, mass spectrometry (MS) and elemental anal. High solubility in organic solvents was observed because of the ester moiety at the peripheral position, and no aggregation was observed over a wide concentration range. The photophysicochem. properties of magnesium (3a), zinc (3b) and gallium (3c) phthalocyanines were examined The highest singlet oxygen quantum yield of 0.66 was obtained for 3c. The photophysicochem. measurements demonstrate clearly the potential of these asym. phthalocyanines as photocatalytic agents in the photodegradation of organic pollutants in wastewaters. The zinc complex (3b) was attached onto silica as a solid support, and photocatalytic degradation studies were carried out using Orange G to provide a typical organic pollutant.

Bonegardt, Dmitry published the artcileHybrid materials of carbon nanotubes with fluoroalkyl- and alkyl-substituted zinc phthalocyanines, COA of Formula: C8H4N2, the main research area is carbon nanotube fuoroalkyl alkylsubstituted zinc phthalocyanine morphol humidity.

In this work, hybrid materials of single-walled carbon nanotubes (SWCNT) noncovalently functionalized with fluoroalkyl- (SWCNT/ZnPc-CF) and alkyl- (SWCNT/ZnPc-CH) substituted zinc(II) phthalocyanines were prepared The effect of fluorination of the substituents in phthalocyanine macrocycle on the functionalization degree of carbon nanotubes and sensor response to ammonia was investigated. It was shown that the type of substituents in the phthalocyanine macrocycle showed noticeable effect both on the degree of functionalization of carbon nanotubes and on the sensing performance of the investigated hybrids. The amount of phthalocyanine mols. adsorbed on SWCNT walls was shown to be 1.5 times higher in the SWCNT/ZnPc-CH hybrid. The SWCNT/ZnPc-CF layer exhibited 2 times less chemiresistive sensor response to ammonia than SWCNT/ZnPc-CH, while its sensor response was more stable at 70% relative humidity.

Regulska, Elzbieta published the artcileNanostructural catalyst: metallophthalocyanine and carbon nano-onion with enhanced visible-light photocatalytic activity towards organic pollutants, Recommanded Product: Phthalonitrile, the main research area is rhodamine B metallophthalocyanine carbon nano onion photocatalysis.

Metallophthalocyanine (MPc) and carbon nano-onion (CNO) derivatives were synthesized and characterized by using UV-visible spectroscopy, IR and Raman spectroscopy, SEM with energy-dispersive X-ray spectroscopy and X-ray powder diffraction. The unmodified CNOs and MPc-CNO derivatives were used as photocatalysts for rhodamine B (RhB) degradation under visible-light irradiation The photocatalytic studies revealed that the MPc-CNO nanostructural materials simultaneously exhibited a high absorption capacity and an excellent visible-light-driven photocatalytic activity towards RhB. These nanostructures possess great potential for use as active photocatalysts for organic pollutant degradation

Mukherjee, Biswanath published the artcileSolvothermally Synthesized Iron Phthalocyanine Nanostructure for High ORR Response: A Joint Experimental Investigation and DFT Analysis, Name: Phthalonitrile, the main research area is synthesized iron phthalocyanine nanostructure ORR DFT electrochem.

In search for replacement of expensive, rare Pt based electrocatalyst towards O reduction reaction (ORR), transition metal-cored phthalocyanine (MPc) were under current research focus. Among various MPc, Fe phthalocyanine (FePc) gives best ORR performance, presumably because of its strong electron withdrawing capability. Herein, the authors report one pot solvothermal synthesis of 1 Dimensional FePc nanostructure and its possible application as ORR catalyst. The ORR performance of FePc nanostructure was carried out in 0.1M KOH (pH = 13) via cyclic voltammetry and linear sweep voltammetry. The performance, which was comparable with com. available Pt/C, measures a half wave potential (E1/2 = 0.64 V vs. RHE), onset potential (Eonset = 0.87 V vs. RHE) and electron transfer number (n) of 3.9 at 0.35 V (vs. RHE), indicating that the synthesized nanostructure essentially promote 4-electron reduction pathway. Addnl., unlike Pt/C, the synthesized nanostructure showed good MeOH tolerance. To elucidate the ORR performance from FePc, 1st principle based DFT calculation on two dimensional FePc monolayer was carried out and presented here for deeper insight. The excellent ORR activity coupled with MeOH tolerance favors the FePc nanostructure as a promising alternative to conventional Pt-based electrocatalyst for future energy storage and fuel cells.

Murmu, Shyamal published the artcileUnveiling the genesis of the high catalytic activity in nickel phthalocyanine for electrochemical ammonia synthesis, Application In Synthesis of 91-15-6, the main research area is catalysis nickel phthalocyanine electrochem ammonia synthesis nitrogen reduction.

Electrochem. NH3 synthesis by the N reduction reaction (NRR) using an economically efficient electrocatalyst can provide a substitute for the Haber-Bosch process. However, identification of active sites responsible for the origin of catalytic activity in transition metal phthalocyanine is a difficult task due to its complex structure. Herein, d. functional theory (DFT) is applied to identify the probable active sites of Ni phthalocyanine (NiPc) for the NRR as well as the origin of catalytic activity which is associated with the d band center and d. of states (DOS) of Ni in NiPc. Accordingly, NiPc nanorods (NRs), synthesized by a solvothermal method in large scale, exhibit an NH3 yield rate ∼85μg h-1 mgcat-1 and a faradaic efficiency (FE) of 25% at -0.3 V vs. RHE. Also, the catalyst shows long term stability up to 30 h while maintaining the NH3 yield and FE. The isotopic labeling experiment and other control study led to validation of the N source in NH3 formation. This study provides brand new insightful understanding of the active sites and the origin of the catalytic activity of NiPc for their NRR applications.

Wang, Bing published the artcileNovel axial substituted subphthalocyanines and their TiO2 nanocomposites: Synthesis, structure, theoretical calculation and their photocatalytic properties, Recommanded Product: Phthalonitrile, the main research area is titanium dioxide nanocomposite electronic transition photocatalytic property.

For the study, we reported the synthesis and characteristics of two subphthalocyanines H12SubPcB-Br (SubPc-1) and H12SubPcB-OPh2OH (SubPc-2), in addition to their resp. composites with nano-titanium dioxide (TiO2). SubPc-1 and SubPc-2 were composed by the measure of hydrotherm with toluene on the scene. The approaches of DFT and TD-DFT were used to research the electronic structure and optical spectra in the subphthalocyanines. The photocatalytic activities of pristine TiO2 particle and TiO2/SubPc composites went through the test to degrade methyl orange (MO) and bromophenol blue (BB) in irradiance of visible light. It is demonstrated from the results that all the TiO2/SubPc photocatalysts exhibited further improved efficiency approx. 72.4% and 29.2% for the degradation of MO and BB under visible light, in comparison with pure TiO2. Furthermore, the reusability studies showed that photocatalytic activity could be maintained over 84% after five recycles.

Yuan, Jie published the artcileActivating Intersystem Crossing and Aggregation Coupling by CN-Substitution for Efficient Organic Ultralong Room Temperature Phosphorescence, Category: nitriles-buliding-blocks, the main research area is activating intersystem crossing aggregation coupling cyano substitution phosphorescence.

Organic ultralong room-temperature phosphorescence (OURTP) has boomed recent advances of organic optoelectronics with the significant breakthrough in facilitating the intersystem crossing and stabilization of triplet excitons of purely organic materials. However, it remains a challenge in revealing the inherent mechanism of OURTP and the general mol. design principles of OURTP materials have yet to be reached, largely owing to the rather complicated and varied OURTP mol. structures. Here, we propose a facile strategy to design efficient OURTP materials by simply introducing a cyano group (CN) on benzene. On the basis of these very simple OURTP mols., it was found that the simultaneously enhanced intersystem crossing and aggregation coupling are two intrinsic prerequisites in realizing the efficient OURTP. The first observation of the excimer emission from the stabilized singlet excited states offers an important evidence for the mechanism study of OURTP, and the direct CN substitution on the benzene ring would be highly instructive for designing efficient OURTP mols.

Yu, Yancheng published the artcileInsight into the binding mode of HIF-2 agonists through molecular dynamic simulations and biological validation, Recommanded Product: Phthalonitrile, the main research area is hypoxia inducible factor agonist mol dynamic simulation; Agonist; Binding mode; HIF-2; Molecular dynamic simulations.

Hypoxia-inducible factor-2 (HIF-2), a heterodimeric transcriptional protein consisting of HIF-2α and aryl hydrocarbon receptor nuclear translocator (ARNT) subunits, has a broad transcriptional profile that plays a vital role in human oxygen metabolism M1001, a HIF-2 agonist identified by high-throughput screening (HTS), is capable of altering the conformation of Tyr281 of the HIF-2α PAS-B domain and enhancing the affinity of HIF-2α and ARNT for transcriptional activation. M1002, an analog of M1001, shows improved efficacy than M1001. However, the cocrystal structure of M1001 and HIF-2 has some defects in revealing the agonist binding mode due to the relatively low resolution, while the binding mode of M1002 remained unexplored. To in-depth understand agonist binding profiles, herein, the mol. dynamic (MD) simulations was applied to construct a stable agonist-protein model, and a possible binding mode was proposed through the anal. of the binding free energy and hydrogen bonding of the simulation results. Nine compounds were then synthesized and evaluated to verify the proposed binding mode. Among them, compound 10 manifested improved agonistic activity and reduced toxicity compared to M1002. This study provides deep insight into the binding mode of such HIF-2 agonists, which would be useful for designing novel agonists for HIF-2.

Titanium dioxide/phthalocyanine (TiO2/Pc), TiO2/fluor containing phthalocyanine (TiO2/FPc), and TiO2/fluor containing cobalt phthalocyanine (TiO2/FCoPc) had been successfully fabricated by a simple combination of phthalocyanines obtained by insitu synthesis on the surface of TiO2 nanofibers prepared by electrospinning. SEM micrographs and X-ray diffraction anal. indicated that the phthalocyanines uniformly immobilized on the surface of TiO2 nanofibers. Photocatalytic activity of TiO2, TiO2/Pc, TiO2/FPc, TiO2/FCoPc nanofibers for methylene blue in water was comparatively investigated firstly by ultravioletvisible absorption measurements with time, and kinetic parameters were calculated Results indicated that the obtained TiO2/Pc, TiO2/ FPc and TiO2/FCoPc exhibited high photocatalytic activity for the degradation of methylene blue and TiO2/FCoPc was found the best. It showed similar or higher activities than related studies and can be suggested as a promising candidate for environmental and energy applications.

A novel synthetic strategy for low-symmetry phthalocyanines was developed, which involves the base-promoted cyclization of a preconnected trisphthalonitrile and a free phthalonitrile in the presence of a metal template. By using this [3 + 1] mixed cyclization approach, a series of zinc(II) phthalocyanine derivatives were synthesized in up to 12% yields, including a very rare ABCD-type phthalocyanine and an amphiphilic ABAC-type analog that can self-assemble in aqueous media, forming stable spherical nanoparticles.
